Limits
LINE LENGTH
The maximum line length is determined by the voltage drop along the cable. To determine whether or not there is enough voltage in the module, voltage between
2 and 0 wires must be over 13 volts. The voltage drop for 40180 and 40181 cables is based on the following formula:
dV = S x L x l
Where: L means the length of the cable,
S means the conductor section; and
dV means the voltage drop measured in volts, which must be under 3.
The maximum length of the BUS must be 125 m. If you need more cable length, make a "star-shape" installation.
INSTALLATION ELEMENTS
The maximum number of modules supported by an installation will depend on their individual consumption. This consumption will determine the type of power
supply. The intensity along the cable will limit the length of the line, according to the formula of the previous section
intensity of the power supply cables (2 and 0) is 7 A.
central unit (for DIN rail)
central unit (for ø60 mm box)
MAXIMUM POWER OF THE INSTALLATION
The maximum permissible intensity of the power supply cables (2 and 0) is 7 A. Therefore, the maximum power provided by the power supplies will be
105 W.
Make sure you remember to connect the cases of the EGi elements to the ground wire of the installation.
DOMOS2 equipments must be installed according to the ITC-BT-51 norm on "Installation of automation, energy management, building and home
security systems", compliant with the Spanish REBT standard ("Electro-technical Regulations for Low Voltage"), in accordance with RD 842/2002.

WARNING:
Please be very cautious when
connecting the BUS.
